The Duke and Duchess of Cambridge and Prince Harry have visited the Hertfordshire studios where all eight Harry Potter films were made.

Around 500 guests from The Duke and Duchess of Cambridge and Prince Harry’s charities joined their Royal Highnesses for the tour of 'Warner Bros. Studio Tour London - The Making of Harry Potter' at Leavesden Studios, Watford, on Friday 26 April 2013.

Warner Bros.’ £100 million facility, the first of its kind to be built in the UK in 70 years, accounts for a third of the dedicated major feature film production stage space in the UK and is the only film studio in the country to be owned and operated by a major Hollywood studio.

Formerly the production home of all eight Harry Potter films, Goldeneye, Star Wars Episode 1 - The Phantom Menace and Tim Burton’s Sleepy Hollow, the state-of-the-art studios now encompass nine sound stages, a 100 acre back-lot and one of the largest underwater filming tanks in Europe.

It is available to all kinds of productions, not just Warner Bros., from commercials to music videos, TV shows to feature films. The first production to shoot there since the redevelopment was All You Need Is Kill, directed by Doug Liman and starring Tom Cruise and Emily Blunt.

Warner Bros. Studio Tour London – The Making of Harry Potter is the only attraction that takes guests behind the scenes of the Harry Potter films and showcases the incredible British talent, creativity and artistry that went into bringing the series to life.
